A Guide to Buying Instantaneous Hot Water Systems

If you’re contemplating upgrading your hot water system, it’s likely that you’re considering an instantaneous hot water system. However, with the number of variations of this system on the market, it’s not always obvious which one will suit your specific needs and use case. This guide will discuss the various aspects of instantaneous hot water systems, from their benefits and drawbacks to installation and maintenance, allowing you to gain a more thorough understanding of these systems and make an informed decision when purchasing one for your home.

What Are Instantaneous Hot Water Systems?

Instantaneous hot water systems, also known as tankless or continuous flow hot water systems, provide hot water on demand without the need for a storage tank. These units heat cold water as it passes through a series of coils within the system, delivering hot water instantly whenever you turn on a tap or appliance that uses heated water.

The Benefits of Instantaneous Hot Water Systems

There are several main advantages to installing an instantaneous hot water system in your home, including:

  • Energy efficiency – Because they only heat the water needed at any given time, tankless systems use less energy than traditional storage tanks.
  • Space-saving design – With no bulky storage tank required, these compact units can easily fit into small spaces such as under sinks, inside cupboards or in garage spaces.
  • Continuous supply – Unlike traditional tanks that may run out of hot water after prolonged use, instantaneous units provide an endless supply of hot water.
  • Longer lifespan – Due to fewer components being subject to wear and tear over time compared with traditional tanks, most tankless models last between 15-20 years.

The Drawbacks of Instantaneous Hot Water Systems

Despite their numerous benefits, there are some potential downsides to consider before investing in an instantaneous hot water unit, including:

  • Higher upfront cost – The initial purchase price is generally higher than that of a traditional storage tank.
  • Limited flow rate – Some models may struggle to provide sufficient hot water for simultaneous use in multiple areas, such as bathrooms and kitchens.
  • Installation requirements – Gas-powered units often require specific venting arrangements, while electric systems may need upgraded electrical circuits.

Available Types of Instantaneous Hot Water Systems

There are two main types of instantaneous hot water systems available on the market:

  • Gas-powered – These systems use natural gas or LPG as their fuel source and typically offer higher flow rates than electric models. They can be installed indoors or outdoors, but they require proper ventilation if placed inside.
  • Electric-powered – Using electricity to heat the water, these units are generally more compact than gas models but have slightly lower flow rates.

Factors to Consider When Choosing an Instantaneous Hot Water System

Before purchasing an instantaneous unit, it’s essential to consider the factors that will impact its suitability for your home, such as:

  • Hot water demand – Assess your household’s typical daily usage patterns and choose a system with a suitable flow rate capacity.
  • Energy efficiency rating – Look for products carrying high energy star ratings to ensure maximum efficiency and long-term savings on your energy bills.
  • Installation location – Consider where the unit will be installed, whether indoors or outdoors, along with any necessary ventilation or electrical requirements.
  • Warranty period – Choose a model backed by an extended warranty period from a reputable manufacturer.

Maintenance Tips for Your Instantaneous Hot Water System

To keep your system running at peak performance and extend its lifespan, regular maintenance is crucial. Maintenance tips include:

  • Schedule annual servicing by qualified technicians who can thoroughly inspect all components and perform any necessary repairs or replacements.
  • Clean filters regularly according to manufacturer guidelines. This will ensure optimal operation without any interruptions.

Conclusion

Instantaneous hot water systems offer a range of benefits that make them an attractive option for homeowners. By considering the factors outlined above and conducting thorough research on available models, you can find the perfect system to suit your specific needs and enjoy energy-efficient, continuous hot water for years to come.
